UNITED STATES PATENT OFFICE BATTERY TERMINAL PROTECTOR Robert Lockyer, Point Edward, Ontario, Canada' Application March 30, 1929. Serial No. 351,221

lClaim. (01.'136-163) This invention relates to covers or shields dematerial between the opening 13 and the rim or signed to be placed lover battery terminals and margin of the shield is slit as at 14 to thus perthe general object of this invention is to provide mit the two walls on each side of the slit to be a shield or cover of this character of rubber or deilected and permit the shield to be disposed rubber composition formed to provide a box-like over a battery post and the cable to pass through -55 member open on the bottom and having at one the opening 13. portion thereof an opening through which bat- Then the walls are permitted to return to their tery cables may extend, said shield acting to normal position in one plane which practically prevent moisture and foreign matter coming in closes this slit 14. Preferably, the two margins lo contact with exposed metal parts and battery oi the slit 13 and the margins of the opening ,13 60 connections, thereby keeping these parts in conare reinforced by an additional thickness .-oi dition which will preserve them and such a rubber designated 15. shield further acting to prevent any short cir- Of course, the form of the opening 13 will cuiting between the positive and negative posts depend upon the form of the battery connection l5 or connections or between these posts and any 0r Cable leading therefrom. The Cable leading 65 exposed metal parts. from the negative post is usually in the form of A further object is to provide a shield of rubber a flattened braid and in that case the opening 13 having an opening through which thev battery as shown in Figure 4 is rectangular in form wherecable may pass, this opening, of course, being as the cable leading frpm the positive pole is shaped to correspond to the positive or negative usually circular in cross section and hence the 70 cable, and the material constituting one wall of opening 13 is circular in those covers which are this opening being split to the edge of the 'shield designed to be placed over the positive pole. so that the shield may be opened at this point Under some circumstances, as for instance in to permit it to be placed over the negative or the batteries used on Ford cars, the cable extends positive cable as the case may be. radially from the battery post, in which case the 75 Other objects will appearin the course o1' the cover may have the form shown in Figure 3. In :following description. other cases the cable extends tangentially from My invention is illustrated in the accompanythe battery post, in which case the opening 13 ing drawing, whereinzwill be disposed aty one end of one Wall of the Figure 1 is a vertical sectional view oi a batcover.

They 'with my invention; y are intended to conform to the shape of the cables Figure 2 is a side elevation thereof; extending from the battery terminals.

This shield is so shown as approximately rectangular, though it formed as to permit it to be attached to the batmay beoi any desired form.

The shield 95 and the lower edge of the shield has the reinforcwill prevent moisture and foreign matter coming ing or thickened portion 12. At one point the incontact with exposed metal parts, with the batshield is provided on one of the side or end walls teries and cable connections, thereby keeping l 11 with an opening 13 through which the cable these particular parts in a condition thatwill connection to the battery post may pass. The preserve them and prevent any short circuiting 100 either between the positive and negative posts and connections or between the posts and any metal construction which may immediately surround the battery, such as metal frames or other devices for holding and carrying the batteries. These connections and all fixtures are very liable to become covered with moisture and foreign matters which are conductors of electricity and these are liable to cause short circuits in and around the storage batteries. These disadvantages are completely obviated by the use of these shields.

I claim:-

A shield for battery posts and the cable connections thereof formed of one integral piece of semi-flexible rubber, the shield comprising a boxlike body entirely open at its bottom` the body having only a top wall and side walls, the inner faces of the side walls extending straight downward to the lower edge of said side walls whereby the opening dened by said side walls is equal to not less than the full cross sectional area of the body to thus permit the side walls at their lower edges to rest fiat against the face of a battery cover` one of the side walls being formed with an opening for and fitting a cable connection, the material of this side wall being slit from the lower edge of the wall directly upward into said opening whereby the shield may be expanded around the cable connection when putting the shield in position.
